【 摘 要 】

The massive access of distributed photovoltaic power station poses a great challenge to the safe operation of the power grid, and the real-time and accurate data transmission is the first trouble to be solved. In this paper, through the establishment of distributed photovoltaic power station data collection system, a set of voltage transformer and current transformer are used to collect data on scene, through middle register at the same time guarantee the data synchronization, through the AD converter is converted to a digital signal after through the WiFi or GPRS data transmission based on conditions in the field. A distributed photovoltaic power station in Jincheng area as an example, it represents that the system has a certain advantage in data realtime, accuracy, overcome the previous system synchronization, real-time data transmission and low accuracy of shortcomings, at the same time in many related power grid applications have a certain role in promoting.
